IMPRQVEMENT IN HORSE HAY-RAKES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it' may concern.-

Be it known that l, JOHN I. MUNROE, of Woburn, in the county of Middlesexand State of Massachusetts, have invented new and useful Improveents in Hay-Rakes; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the saine, reference being had to the accompanying drawings making a part of this specification, in which- Figure 1 is a top or plan view;

Eigure 2 is a side elevation;

Figure 3 is a detached vertical section of a tooth and its metallic tip; and

Figure 4 is a detached transverse section of the tooth-brackets, taken on the line Y Z, fig. I.Y

Similar letters indicate like parts in the' several figures.

The nature of my invention consists in certain improvements upon the hay-rake patented by me in the year 1867, known as an independent-tooth rake;

the said improvements consisting mainly in pivoting' the seat in uprights formed rigidily upon the tiltingbar, and combining a pivoted stirrup therewith.

1n the drawings- A A represents thc wheels, and

B, the axle.

G C are the shafts or thills, and

D a bar in which the shafts are secured, and

E represents two uprights, in which axle B revolves, and upon which bar D is securely fastened.

F represents stays or braces which pass from uprights E to the shafts C, as shown.

I 4represent-s stays pivoted at their forward ends to shafts C, while the bar G, extending across' the rake,

is firmly attached to tholrrear ends.

H is the divider-head, which is attached by a spring hinge to bar G,and

0 are the teeth of the divider.

The foregoing parts being substantially thc same as in the rake patented as above stated, a more particular description is not deemed necessary.

o represents rubber buffers, which are inserted in bar G at the points oi' contact with braces F, or rice versa, so that, when the divider is raised, the buffers shall reduce the shock, and mufllle the sound produced by the sudden raising of the divider.

J J are metallic supports, in which the rod a is supported.

1t l are metallic couplings, the two prongs of which are pivoted upon rod a, while the teeth-bars L are bolted to the broad portion between the vertical flanges, as is plainly shown in fig. 4.

I) is the wooden portion of the teeth proper, this portion being connected with the bars L at a suitable acute angle, as shown, and their `)'oiningf being strengthened by the short stay c.

Upon the lower ends of teeth 11 is secured a-metallic socket-point, d, by which the teeth are protected from wear or splitting, and in the performance of various kinds of work their penetrability is such that the working of' the rake is more satisfactory than with any other teeth.

M is a rocking-bar, which is pivoted to the rod a.

rlwo arms, f j, of this bar extend back, and are attached to the tilting-bar S placed beneath the tooth' bars L, and the arm e extends forward, and the chain l) connects it with the divider, as shown.

j is a stirup, or foot-rest, which is pivotcd in the .forward end of arm e, while q g are two uprights rigidly attached to or formed uponbar M.

Between these upright-s is pivoted the drivcrs seat, h, which is balanced upon the pivot i.

k is a hand-rail, the forward end of which is secured in bar M, from whence it passes by an upward curve to the rear of seat 71., around which it passes, and thenceby a downward curve to bar D, in which it is secured.

When in use, and the operator is in scat h, he will guide the horse wit-b -his left band, and with his right support himself` by the rail k, having one foot in rest j, and the other upon either of the platforms l or on, and when it is desired to raise the rake-teeth to pass the windrow, or for other purposes, he will throw his weight forward upon the rest j, being aided by his grasp upon rail 1.', and retaining his seat. He willthus depress the' front end and raise the rear end of bar M, whereby the rake-teeth will be elevated, and the divider lowered to the ground, and the latter will clear the `space in front of the windrow of the hay, while the rake-teeth pass the windrow, so that the rake-teeth drop into the space thus cleared, and leave Sno hay trailing behind.

When the operator desires to lwer the rake-teeth, it is done by the saine means, but by an inverse movement of the body to that of raising them, so that the weight of the operator, by a relative change of position', actuates the rake-teeth, as described.

'llhechain P may be so attached to a hook or other device that both the rake and divider-teeth shall be held suspended from the ground for the purpose of transport-ation, and the divider may by the same means be suspended, if it be desired to use the rake separately.

The elastic buffers n, which are inserted in tiltingbar S beneath each tooth, prevent shocks and noise when raising or lowering the rake-teeth.

Having` fully described my invent-ion,

NVhat I claim as new, and desire to secure by Letters Patent, is-

The combination of seat h, pivoted in uprights g g, formed rigidly upon tilting-bar M, with pivoted stirrup j, substantially as and for the purposes specified. J. I. MUNROE.
